Molecular phylogenetics suggests the following relationships of tribes, subtribes and genera:[6][7][8][9]Nuytsia is sister to the rest the Loranthaceae,[10] with many characters, including its pollen, its fruit (dry and three winged), and the number of its cotyledons, differing substantially from all other Loranthaceae genera.[5] The root parasitic habit is thought to be the basal condition of the family.,[5] with the stem/branch parasitic habit evolving ca. 28-40 million years ago.[5][11] However, Grimsson et al. (2017)[12] estimate this as occurring somewhat earlier (ca. 40-52 million years ago).
Kingella is listed as a synonym of Trithecanthera Tiegh by Plants of the World Online.[14] Also Ixocactus is listed as a synonym of Phthirusa Mart.[15] and Tetradyas is listed as a synonym of Cyne Danser.[16]
